Back Ground Image Of Main Menu Changed When Use Urdu As A Language

when i use this line in views/layouts/main.php

my css is changed css means its background image became large .just including this if i write any other line it does not effect the css and this is only during urdu writing in english this error is not occured.

how this will be consistent??

before and after login the image looks like this.

array(‘url’=>array(’/cartoon/create’), ‘label’=>‘اپ لوڈکارٹون’,


i attach images after and before login .after login it change due to the above line.
